You can earn an additional point by pursuing Option 2. You’ll need to meet the requirements for Option 1, and install submeters for at least one water subsystem, such as the following:
Implement a tracking process to collect water usage data on at least weekly intervals from water meters. You can record data automatically with data logging equipment or by manual meter readings.
For both credit options (see below), ensure that any meters owned by the building are functioning properly by following the calibration recommendations from the manufacturer. Meters owned by utilities or other entities are exempt from this requirement.
Identify all meters in the building and associated grounds, and record their location, date of installation, and ownership. This will help you complete the LEED Online credit form and determine whether any of the meters owned by the project building are due for calibration based on the manufacturer’s recommended interval.
Consider both Option 1 and Option 2 for your project building. Option 1 involves a single water meter for the whole building and grounds, and is easier than Option 2, which requires metering at least one subsystem such as irrigation or the cooling tower. See information on both options below.
